| titleOfInvention | Tin soldering point alloying forming method |
| abstract | The invention discloses a tin soldering point alloying forming method. The method takes the pad material as the tin soldering point alloy to form an alloyed metal source, forms alloying treatment in the reflow process, combines the alloying of the tin soldering alloy and the reflow process in the solder joint forming process into a whole, and simplifies the process. After the welding spot is formed by the alloy and copper, the welding spot formed by the alloying method is doped with graphene, so that the thickness of intermetallic interface compounds formed at a brazing joint is smaller, the reliability of the welding spot can be improved, the joint interface formed by welding is stable, the tissue is uniform and fine, and the falling resistance is excellent. |
